TxoLED GlareLos ntawm kev tsim kho qhov muag: Cov Ntsiab Lus, Txoj Kev, thiab Kev Coj Ua Tshiab

Glare tseem yog ib qho tseem ceeb tshaj plaws uas tsis tau pom dua cov teeb meem hauv LED teeb pom kev zoo. Cov ntaub ntawv pov thawj qhia tias ntau dua 60% ntawm LED teeb pom kev tsis txaus siab cuam tshuam txog qhov ci ntsa iab, nrog kev tswj tsis zoo ntawm lub ntsej muag tsis yog tsuas yog ua rau pom kev tsis xis nyob tab sis kuj tseem ua rau muaj teeb meem kev noj qab haus huv xws li mob taub hau thiab qhov muag. Nyob rau hauv txoj kev teeb pom kev zoo, glare ntau dhau tuaj yeem ua rau muaj kev pheej hmoo ntawm kev sib tsoo los ntawm 15-20%. Kab lus no tau tshuaj xyuas xya engineering-validated LED anti-glare tsim txoj kev, xws li los ntawm microstructural optimization mus rau theem nrab optics tsim thiab ntse dimming algorithms, txhawb los ntawm cov ntaub ntawv kawm ua qauv qhia yuav ua li cas sib npaug kev ua tau zoo nrog kev pom kev nplij siab.

1. Optical Mechanisms ntawm Glare Tsim

1.1 Direct vs. Reflected Glare

LED glare manifests nyob rau hauv ob hom thawj:ncaj glare(lub teeb qhov muag ncav cuag qhov muag ncaj qha) thiabreflected glare(secondary reflections los ntawm siab -reflectance nto). Kev ntsuas qhov muag pom pom qhov tsis xis nyob tshwm sim thaum LED nto luminance tshaj 10,000 cd / m² nyob rau hauv ib txwm saib cov ces kaum (45℃-85℃). Hom LED chips tso tawm 50,000-100,000 cd / m²-ntau tshaj qhov kev nyab xeeb.

1.2 Kev ntsuas qhov tseem ceeb

UGR (Unified Glare Rating): CIE's pom zoo sab hauv tsev glare tus qauv:

UGR=8log[0.25/Lb × Σ(L²ω/p²)]

Qhov twg L yog luminance, ω yog lub kaum sab xis, thiab p yog qhov ntsuas qhov ntsuas. Cov chaw ua haujlwm xav tau UGR<19, precision work areas UGR<16.
